This is a wound that comes from someone using black magic to harm their opponent, usually the wision is thrown in front of the victim's door or path. If the victim walks past then it hits! Starting with a small wound that swells the foot very much and eventually the foot has to rot completely. I recently had a case that had been cut several times at the ok for the infected wound. Through messenger I told her already this is a wisi soro and when she came to me it indeed turned out to be so. Meanwhile, she has already recovered completely .I hope that herself through me page shares her experience with me with you. Using nengre kondre sabi nanga ingi sabi, the yorka running along with this soro was removed and all the debris was sucked away by the obia.
